≪About operation≫
The operation of the laser treatment apparatus 1 having the above configuration will be described with reference to the operation flowcharts of FIGS. 5 and 6 in consideration of the operation of the operator. Here, when the pre-use inspection mode is selected (step 1 (S011) to step 5 (S015) corresponding to FIG. 5) and when the laser treatment apparatus 1 is activated and operates in the treatment mode (corresponding to FIG. 6). Each of Step 1 (S021) to Step 4 (S024)) will be described.

<Operation flow when pre-use inspection mode is selected>
Hereinafter, the operation of the laser therapy apparatus 1 when the pre-use inspection mode is selected will be described.

(Step 1 (S011))
In step 1 (S011), the user selects the pre-use inspection mode by operating the pre-use inspection switch 21c.

(Step 2 (S012))
In step 2 (S012), the user turns on the foot switch 21b. Thereby, the control unit 27 causes the laser beam output unit 24 to output the first laser beam such as the output corresponding to the pre-use inspection mode and the irradiation time via the current control unit 22.

(Step 3 (S013))
In step 3 (S013), in accordance with the output of the first laser beam from the laser beam output unit 24, the current detection unit 23 detects the current value, and the first light quantity detection unit 25 detects the first laser beam. The light quantity detection, the temperature detection part 26 detects the temperature of the laser light output part 24, and the second light quantity detection part 32 detects the light quantity of the second laser light. Then, the detection results detected in each block are output to the pre-use inspection unit 201.

  When the pre-use inspection unit 201 determines that the detection result of the second light quantity detection unit 32 does not satisfy a predetermined condition, even if laser treatment is performed thereafter, a predetermined output corresponding to the laser treatment is output. This shows that the second laser beam cannot be irradiated to the affected area. Therefore, in this case, the pre-use inspection unit 201 determines that the laser treatment apparatus 1 is “failure” and turns on the warning lamp 29c indicating the failure.

  Further, in the pre-use inspection unit 201, the detection result of the second light quantity detection unit 32 satisfies a predetermined condition, but the current of at least one light source among the plurality of light sources provided in the laser light output unit 24 is determined. When it is determined that at least one of the detection result of the detection unit 23, the detection result of the first light amount detection unit 25, and the detection result of the temperature detection unit 26 does not satisfy the predetermined condition, the pre-use inspection unit 201 performs laser treatment.

This is because the detection result of the current detection unit 23, the detection result of the first light quantity detection unit 25, and the detection result of the temperature detection unit 26 even if the second laser beam is appropriately irradiated in the laser beam irradiation unit 31. That at least one of the above does not satisfy the predetermined condition means that the redundancy of the plurality of light sources of the laser light output unit 24 is not ensured, and there is a failure of the laser treatment apparatus 1 or the like when performing laser treatment thereafter. This is because an abnormality may occur.

  When the pre-use inspection unit 201 performs the above-described failure or abnormality determination, the code display 29e displays the content of the failure or abnormality indicating which component part is the failure or abnormality.

  Further, in the pre-use inspection unit 201, the detection result of any current detection unit 23 of the plurality of light sources provided in the laser light output unit 24, the detection result of the first light quantity detection unit 25, the detection result of the temperature detection unit 26, and If any of the second light quantity detection units 32 satisfies a predetermined condition, the pre-use inspection unit 201 determines that there is no “failure” or “abnormal”.

(Step 5 (S015))
In Step 5 (S015), the pre-use inspection unit 201 displays the result of the pre-use inspection on the display unit 29, and the storage unit 28 stores that the pre-use inspection mode has been executed and the result of the pre-use inspection. To exit the pre-use inspection mode. The end of the pre-use inspection mode may be automatically performed by the pre-use inspection unit 201 after the above-described operation of the pre-use inspection unit 201, and may be shifted to the treatment mode, for example. Alternatively, the pre-use inspection mode may be terminated, and the user may move to the treatment mode by operating the operation unit 20. Alternatively, when the user turns off the power switch 21a and turns on the power switch 21a again, the user may be allowed to operate in the treatment mode.

(Step 1 (S021))
In step 1 (S021), the user activates the laser treatment apparatus 1 by operating the power switch 21a. As a result, the laser treatment apparatus 1 becomes operable in the treatment mode.

(Step 2 (S022))
In step 2 (S022), the pre-use inspection execution determination unit 202 extracts data related to the previous activation from the data in the storage unit 28.

(Step 3 (S023))
In step 3 (S023), the pre-use inspection execution determination unit 202 determines whether or not the pre-use inspection has been performed when the laser treatment apparatus 1 is started up last time.

(Step 4 (S024))

  Specifically, it may be determined whether or not a pre-use inspection is performed at a predetermined number of consecutive (for example, three) past activations including activation immediately before the current activation. Further, it is determined whether or not a pre-use inspection is performed at a plurality of past activations including the activation immediately before the current activation performed within a predetermined past period (for example, within 72 hours) from the current activation. May be.

  For example, after performing a pre-use check at a certain start-up and before starting to perform treatment using the laser treatment apparatus 1, the power of the laser treatment apparatus 1 is turned on at least once, and the pre-use check is also treated. It is conceivable to turn off the power without performing the operation in the mode. In this case, the pre-use inspection is not performed at the time of the previous activation, but it is considered that there is no particularly great change in the state of each part of the laser treatment apparatus 1 from the most recent pre-use inspection to the present.

  For this reason, in such a case, the pre-use inspection execution determination unit 202 performs a plurality of consecutive past activations that have been performed continuously, or a plurality of past operations performed within a predetermined past period from the current activation. In any of the startups, it is determined whether or not a pre-use inspection has been performed, and if a pre-use inspection has been performed, it is determined that the use inspection for the current start has been performed. Also good.

  In addition, in the case where the pre-use inspection is not performed at the time of the immediately preceding start-up, the pre-use check is not performed for some reason between the last pre-use check and the current start-up. It is conceivable to emit two laser beams.

  In this case, the pre-use inspection execution determination unit 202 may determine whether or not the pre-use inspection is performed based on whether or not the second laser beam is irradiated. For example, the pre-use inspection execution determination unit 202 may perform any of a plurality of consecutive past activations or a plurality of past activations performed within a predetermined past period from the current activation. When the pre-use inspection is performed and the second laser beam is not irradiated, it may be determined that the pre-use inspection corresponding to the current activation has been performed.

  Further, even when the second laser beam is irradiated once or a plurality of times, if the total irradiation time is short, it is considered that the light source hardly deteriorates. In this case, similarly, it may be determined that the pre-use inspection corresponding to the current activation has been performed. On the other hand, when the total irradiation time of the second laser light is greater than or equal to a predetermined value, it is considered that there was an operation that could cause degradation of the light source performance after the previous pre-use inspection. In this case, it may be determined that the pre-use inspection corresponding to the current activation is not performed.

  INDUSTRIAL APPLICABILITY The present invention can be applied to various therapeutic devices and diagnostic devices, and can be suitably used for therapeutic devices and diagnostic devices capable of suppressing the possibility of failure during treatment or diagnosis and capable of performing appropriate operations. .
